The vehicle's battery provides the power required to start the engine, and power all the electrical components in your Mitsubishi.

Mitsubishi Starter Motor Failures

You can tell if your starter motor has an issue or not usually by listening, if you hear a clicking noise when you turn the key or a grinding noise during the startup, or your vehicle can start, but only intermittently then the starter motor may very well be the problem.

Mitsubishi Fuel System Complications

Your Mitsubishi uses a combustion engine, and for that reason to start and run, it needs a mix of enough fuel and air. If your Mitsubishi problems are the result of a faulty fuel system, this can sometimes be a clogged fuel filter or a faulty fuel pump relay, which could suggest the engine may not be receiving the fuel it requires to get the car going.

Mitsubishi Electrical System or Wiring Problems

These can be some of the numerous electrical reasons your car won't start.

If it’s a battery issue you suspect is the cause of your troubles, then the first thing you should do is inspect the battery and check the battery terminals. You want them to be clean, not corroded and firmly connected. If you discover that the terminals are indeed corroded you can try to clean them up with a mix of baking soda and water. You will need to replace the battery if it's old or weak, otherwise even if you charge it up enough to start the vehicle, it will probably run out of life again in the not-so-distant future. You can use a multimeter as a way to test the life of the battery to see if it’s worth saving or if it needs replacing. You can ask a reliable car mechanic online or locally to best advise you on this.

If the alternator is what you suspect is the culprit, you can test it. If you can get the car to start up temporarily (you may need to jump start the car for that), but when it’s going, let the vehicle run, and while its running, disconnect the positive terminal of the battery. It's most likely because of a fault with the alternator if you find your Mitsubishi dies pretty quickly when you disconnect the positive terminal. You should be aware however that this method can be risky and dangerous, and might damage the sensitive electronic components in your Mitsubishi, so it's best to consult with an experienced car mechanic in your area or online, before ever attempting this.

You should hear a humming sound for a couple of seconds. It might be there is an issue with the fuel pump if you are unable to hear this noise.

If various warning lights show up on your dashboard, it might be because of a damaged sensor.

Try to drive your vehicle regularly to keep the battery full of juice. If you remember you haven't driven your car in a while, take it for a spin to ensure there is still a charge in the battery. Worth noting: letting the battery totally drain, is also damaging to the longevity of the battery, try not to do this.
